This invention relates to closures and particularly to closures andclosure structures especially adapted for use in connection withbottles, jars, or similar fluid receptacles.

Among the objects of the present invention which is simple inconstruction and operation and'readily suited to economic manufacture.

7 Another object of the presentinvention is to provide a closure adaptedfor substantially 'manently secured by wire or the like, to therceptacle instead ofth'e usual shipping 010- sure.

Anotherobject of the invention is to provide a closure supportingstructure whereby the closure may be retained in sealing position withrespect to the receptacle and Wheree by releasing from such positionwill automatically cause the closure to assume a position free frominterference with the discharge of material from the receptacle;

Other objects of the invention include t h combination and interrelationof parts whereby the Whole forms a convenient readily attachable anddetachable simple structure, and as the closure is retainedincombinationwith the receptacle, contamination z of the closure is prevented'whensterileliq- .uids are used and thus the device isparticu- I 1 'larlyadapted for medical-use, andan easily locked closure is obtained bysimple down ward pressure on the knob thereof.

With these and other objects of the present inventionin view, referencemaybehad to the accompanying'drawings, in which Figure 1 is aperspective view of one form of my present invention;

Fig. 2 is a verticalsectional view of that form of the inventionillustrated in Fig. 1;

trated in Fig. 3, and

Fig. 3 is a top plan View of the closure base as will be hereinafterdescribed;

Fig. 4 is a side elevation of. the base illus- Fig. 5 is teamperspective view. of a I sealing bushing adapted for %LSS 0O1a.tlO11W1th said base- Referring'more particularly to the-drawiii-gs, thepreferred embodiment of my invention" herein; illustrated, includes abase illustrated in detail in Figs. 3 and l. The base includes anelongated horizontally posit tioned transversely extending-member 11,depending from which there is provided a tub ular sleeve 12 crimpedthroughthe aperture of the rnember 11,and is adapted to be surrounded bya sealing bushing 13, as illus trated in Fig. 5, which is preferablyformed of cork, rubber, or other suitable semi-flexibleniaterial. Thetubular portion or sleeve '12 and the bushing 13 are. adapted to bereceved within the neck of a receptacle which has beenillustrated-'in'the" form of a bottle 1 1. The tubular portion 12and'bushing 13areremovably secured within the neck of the bottle andsealed relatively thereto through the bushingJB, which through its Vexpansive character retains the base thereon.

Associated with one extremlty of the meme p ber ll, a spring. closuresupporting'member l5 'is' 'provided, hingedly associated therewithasindicatedat 16. 7 The member 15 is preferably formed of spring metal,such as steel or the like, and is bowed upwardly, the free 1 end beingadapted I for engagement" with the free end of the member '11, asindicated at 17.2. The removableengagement of the free end of the; bowedmember .15 with the; ex: tremity of the member'llis provided for by aninwardly turned portion 18 thereof with 'which'is associated agfinger,manipulating BX- 'tremity, 19. lfThefi central portion of 'thebowedmemberf15iscentrally apertured as at 20as shown in F. ig 2,toreceive therethrough afthreaded member .21, the head "offwhichispositionedidownwardly and engages a washer 22 through the medium ofwhich a" compressible stopper 23' is engaged in association withthethreaded member 2l-and the bowed member 15. Theupper-end of the threadedmember 21 is provided with a knob 24, preferably formed of heavymetallic material, the knob being secured in association with the bowedmember 15 and the threaded member 21 by the provision of a threadedretainer associated with the member 21, or the'knob 24 may be threadedto accomplish the purpose of the retainer 25.

The stopper 23 is preferably formed cork, rubber, or other suitablecompressible material, whereby the member may be forced into tightengagement with the upper portion of thetubular member 12 of the base10,

and thus prevent the flow of liquid there through. The stopper'23 iscovered by a metallic cap 26 which will hold the stopper 23 with themember 21. The heavy characteristic of the knob 24 is adapted to controlthe position of the bowed member'15- when the stopper isout ofengagement with the tubular portion of the base The arrangement is suchthat the center of gravity of the bowed member 15 is outward form thehinged portion 16 thereof after slight upward movementof the knob 24.Thus after disengagement of the-portion 18 from the point 17, the'bowedmember 15 will pivot about thehinge 16 and assume the position indicatedin dotted lines in Fig, 2.

The springy characteristic of the bowed member 15 and the configurationthereof with respect tothe portion 11, is such that for engagement ofthe portion 18 at-17, downward flexing of the bowed member 15isnecessary. Thus the stopper 23 is retained within the tubular portion12, and upon releasing the catch portion 18, a reflexing ac-. tion ofthe bowed member 15 takes place, thus urging the removal of the stopper23 from the tubular portion 12 and throwing the bowed member 15backwardly, whereby the center of' gravity will be outward from thehinged portion 16, as hereinbefore described, whereby the bowed memberand its associatedstopper and knob assume the posi- 'tion indicated bythe dotted lines in Fig. 2.

Locked closure of the device is accomplished by simple downward movementof the knob 24 andpressure thereon.

' From the foregoing 1t will be readily seen that my'presentinventionprovides an imof a transversely extending base carried thereby,and a closure member pivotally associated with one end of said base andengageable with the opposite end of said base, said member having aflexible arm and a closure plug carried by said arm.

2. In a closure for receptacles, a receptacle-engaging element includinga transversely-extending base, a flexible closurecarrying memberpivotally attached to one end of said base, said closure-carrying memberhaving a catch at its free end adapted to engage the corresponding freeend of said base thereby retaining said closure-carrying member in aflexed position on said base.

3; In a closure for receptacles, a receptacle-engaging element includinga transversely-extending base provided with a 1ongitudinal depression toform a spout, a flexible member pivotally attached to one end of saidbase,,a stopper element centrally secured to said flexible memberat oneside thereof, a weighted manipulating element centrally secured to saidflexible member at the other side thereof, a catch formed by the provedautomatically operable bottle stopper which may be readily associatedwith various kinds and configuratlons of receptacles w thout clamping 7means or extra securing devices. iii It will be readilyunderstoodthat'the in vention as herein disclosed may undergo variouschanges andmodlficat ons and the full useor equivalents be resorted towlthoutjdeparting from the spirit or scope, of t pended claims.
